Is this tv a good deal?

It's so it can play 24hz content.

 

Sorry for the bolding but I've explained this on this forum many times.  Firstly, let's go to LTT's own recent video on frame times:

 

 

We all know about frame times, right?  Digital Foundry reinforces this topic all the time.  A 60hz display refreshes 60 times per second or once every 16.66ms  If your game runs at 60fps locked, you get a frame every 16.66.  If your framerate dips BELOW like 40-50fps you start getting uneven frame times because 60 divides into 60 perfectly evenly, 40 or 50, not so much, so you start getting some frames at 33.33 ms while others are at 16.66ms and that creates a 'judder' as the frequency at which you see new frames jumps up and down.  Because, remember, 60hz display can ONLY refresh at 16.66ms intervals, if there is no new frame, the last frame is held, so it will then be on screen for 33.33ms or 50ms.  This is why for games that can't hit 60hz you often see 30fps locks.  Cause at least then every frame is delivered EVENLY at 33.33ms.

 

Now let's look at most TV and movies... Yup, those are 24hz and your TV is 60hz.  In television we would call what needs to be done a 'pulldown' at a rate of 3:2, so a frame is held for 3 refresh cycles, the next frame for 2 cycles, then 3, then 2 and so on.  Or, timing wise, 50ms, 33.33ms, 50ms, 33.33ms... Yup, each successful frame is not drawn for the same length of time as the last frame so you get judder.  Same 'frame time' issue that has been grilled into you about video games.

 

So, okay, sure your 120hz panel in your TV can't get a 120hz signal for HDMI.  For the uneducated you'd say 'WELL THIS IS CLEARLY A SCAM BLAH BLAH CAUSE I KNOW ALL BOUT THE COMPUTER FRAME RATES'.  But what if we went with a 24hz signal?  Because 24 DOES divide evenly into 120.  It divides 5 times into 120 even.  So we can do a 5:5 pulldown.  Every frame of your 24fps movie will be drawn for 5 refresh cycles.  On a 120hz display each refresh cycle is 8.33ms long, if you use 5 cycles for each frame that's 41.66ms.  Every frame is displayed for exactly for 41.66ms.  Not 33.33, then 50, then 33.33, then 50 and so on like a 3:2 pulldown, but for 41.66ms every time.  No judder from uneven frame times because now the frame times.

Im too dumb to understand that... lmao

It's... It's literally the basic mathmatical division that you learned in the 3rd grade...

I read through it again, and i understand it now but Ive never dealt with buying a TV before which is why it makes less sense
